Custom Dual Battery Relocation Kit Worksheet

When providing lengths, we advise you to carefully consider nice, smooth runs for each cable. You may elect to run a length of wire or string along the actual route for each and then measure that length.

Before beginning, you will need to determine the exact mounting locations for each of the components:

Batteries – Set these up in the location and orientation which they will be installed. Factor smooth cable runs up to the terminals. Factor how battery boxes or other enclosures will affect these runs. Side Post batteries limit flexibility on connecting multiple cables so Top Post or Top / Side Post batteries are always preferred in multi-battery installations.

Power Distribution Block – Cable(s) from the batteries will be run to a Power Distribution Block under the hood for distribution to the starter, accessories, etc. This should be located away from areas of heat and on the same side of the vehicle as the starter is located.

Battery Disconnect Switch – If entering the vehicle in timed events, it’s best to know the rules of the sanctioning body as they pertain to the location of the Battery Disconnect Switch. The switch MUST be located as outlined in the rule book and MUST disable a running vehicle (we’ll take care of you on that part). It is often advantageous to activate the switch with a push/pull bar kit, like our Moroso 74105 Push/Pull Battery Disconnect Mounting Kit. This reduces the amount of cable required thereby reducing weight, resistance, and cost.
